Undercoating & Rust Proofing in Calgary — Stop Road Salt Corrosion — StopTHE RUST.

Yes — undercoating is one of the best-value protections for any vehicle driven in Calgary. Our roads are treated with magnesium chloride brine, road salt, and a gravel 'pickle mix' that cling to your undercarriage and stay corrosive even when dry, attacking frame rails and brake lines year-round. Prevention runs roughly $599–$1,299, while the average rust repair starts at $3,500+, so protecting now costs a fraction of fixing perforation later.

It depends on how you use the vehicle. Oil-based undercoating creeps into seams, pinch welds, and hidden cavities to stop rust from the inside out, and is reapplied annually. Rubberized undercoating forms a tough hard-shell barrier against gravel and road spray that typically lasts 2–3 years. Many Calgary drivers choose our Full Defense package, which combines a rubberized shell with oil-based cavity wax injection for the most complete coverage.

Undercoating starts at $599 for a coupe or sedan, $699 for an SUV or truck, and $799 for exotics. Standalone rust-proofing runs $399–$499, and our complete undercoating-plus-rustproofing package is $999–$1,299 depending on vehicle size. A quick inspection confirms the exact price for your build.

No. In Canada, a dealer cannot void your mechanical warranty simply because you chose third-party rust protection. Our products are applied with exhaust, the catalytic converter, and sensors masked off, so they stay clear of factory components and your coverage stays intact.

Late spring and early summer is the ideal window — it's the perfect time to inspect last winter's salt damage and book before the fall rush. Application bonds best to completely dry metal, so spring, summer, and early fall are all excellent. We can apply year-round, but a winter booking needs a thorough wash-and-dry cycle in our shop first.

Oil-based undercoating is designed to be reapplied annually, since it penetrates seams and slowly works deeper over time. Rubberized hard-shell coating lasts 2–3 years but should be inspected each year, and the internal cavity wax inside doors and rocker panels should be checked annually. We recommend a yearly inspection-and-refresh to keep your protection working.

No. Before application, we carefully mask off the exhaust, catalytic converter, and all vehicle sensors so coating never touches heat-sensitive or electronic components. The product is applied only to frame rails, body panels, suspension areas, and cavities, leaving your vehicle's systems untouched.

Undercoating shields your undercarriage from the corrosive cocktail Calgary spreads on roads like Deerfoot and Stoney Trail — magnesium chloride brine, road salt, and gravel pickle mix. These agents stay corrosive even when dry, driving the three-stage corrosion process from surface rust to deep penetration in seams to permanent perforation. A sealed barrier plus cavity wax stops that process before it reaches the frame.
